In a particular mammal, having long whiskers is a SEX-INFLUENCED trait; in FEMALES, long whiskers is dominant to short whiskers, and in MALES, short whiskers is dominant to long whiskers. Use W for the long whiskers allele and W* for the short whiskers allele. You cross a true-breeding FEMALE with long whiskers to a true-breeding MALE with short whiskers. After intercrossing the F1 progeny, which of the following results are expected for the resulting F2 progeny? a) None of these choices b) 3/8 of the F2 progeny will be males with short whiskers. c) All of these choices d) 1/8 of the F2 progeny will be females with short whiskers. e) 3/8 of the F2 progeny will be females with long whiskers. O f) 1/8 of the F2 progeny will be males with long whiskers.

In some dogs, barking when trailing a scent is a dominant trait. Others dogs do not bark while trailing a scent. Erect ears are dominant to drooping eats. What is the phenotypic ratio of F1 when a heterozygous erect eared silent trailer is crossed with a droopy eared barker whose mother is silent
Suppose the ear length of two populations of jerboas is controlled by one gene. To determine the mode of inheritance, a homozygous short-eared female is crossed with a homozygous long-eared male. Then, siblings from the F₁ are crossed, and the number of short- and long-eared animals are counted to determine the phenotype ratio. Match the phenotypic ratio anticipated in the offspring from a cross of two heterozygous individuals to the appropriate mode of inheritance for the short-ear allele. Mode of inheritance F1 phenotype Cross of heterozygotes 1 long : 3 short Autosomal dominant Autosomal recessive Sex-linked dominant Sex-linked recessive All short-eared 1 long : 1 short All long-eared Answer Bank All short-eared males 1 long : 1 short; females all short 3 long : 1 short Long-eared females, short-eared males
Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced.The probability of obtaining a female or male parakeet is the same as for humans. A green parakeet crossed with a white parakeet produced offspring with four different colour patterns.What is the genotype of the green parakeet? Answer
